As we all know Firebase provides an awesome package of cloud services making the life of developers very easy. There is a wide range of tools available for next-level app development like Authentication, Testing, Analytics, Storage, Database, etc.

In this post, we will create an Ionic Application with Image Upload feature with Progress bar. It will also list already saved of Images. This application will focus on the two most important services of Firebase

In this tutorial, we will implement a very simple Autocomplete feature which is also known as TypeAhead or Suggestion search bar. Typeahead is basically an Input field where user can type and get matching results in a dropdown list to select from.

In our previous tutorial, we discussed how to implement a very basic Routing Module in an Angular 8 application. Here we will go a step further to discuss some more concepts related to Routing in Angular 8 application.

What we are going to create?

Create an Angular 8 application which will have Nested Routing up to three levels. Each level of components has its own Router Module. We will also discuss How to use lazy loading concept in Angular 8 Routing to load components on run time when they are called.

Many modern Javascript based front-end application create Single Page Application(SPA) which loads everything once on the browser after that user can navigate between pages/ views very quickly without loading any HTML or JS content except data.

Checking/ Unchecking a list of items with checkboxes is provided with a master checkbox to provide ease to users to control all list items. Angular Material Checkbox module MatCheckbox proves very handy in creating such lists with a number of properties.

In Material Checkbox module there are three states with Checked and Unchecked which are common, but there is also a third state called Indeterminate which is a middle of these two. Indeterminate Checkbox state indicates that some of the list items are checked but not all. It is indicated with a hyphen (-)in the checkbox.

Here we will create a list of items with a master checkbox using which a user can check to uncheck all item lists. Also if a user checks some of the items but not all, the master checkbox will show Indeterminate state which is very easy to implement.

The tooltip component is a piece of information shown to the user for actions. Tooltips prove very handy for developers to communicate with users with useful messages in the application. The best thing is developer doesn’t need to care about space as they are overlays floating above content.

Angular material provides a number of useful components which are very easy to use after configuration.
